IMPROVEMENT lN TOY BREECH LOADlNG FIRE ARMS.

Specification forming part of Letters Patent No. 835M865, dated April29, 1862.

To (ZZZ whom it may concern.-

Be it known that I, FREDERIO DENZLER, of New York, in the county andState of New York, have invented a new and Improved Parlor-Gun; and Ihereby declare that the following is afull and exact description of thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

Figure I represents a longitudinal section of the gun. Fig. II shows across-section of the gun-barrel, and Fig. III shows a plan of thebreech-piece.

The nature of my invention consists in the arrangement of a movablebreech-piece,wl1ieh contains the shot and the percussioircap, saidbreech being held in its place by a bayonetjoint, and removed away fromthe gun to re ceive the charge.

To bore a hole not larger than the size of a large shot through a solidgun-barrel is a very diflicult operation, particularly when the barrelis of any length. To obviate this difiiculty, and at the same time toobtain a true and smooth hole, I make the barrel of two pieces, a b, ofhalf-round iron, and plane out of each piece a groove of the requiredsize, so that when both pieces are fitted together these grooves shallform the required hole or bore of the gun-barrel. The two parts a and b,Fig. II, are then fastened together by small pins or dovetail pieces,and a metal tube, a, forced over the same, after which the joints aresoldered together with tin or any other soft solder. This barrel is thenscrewed into the breech B in the usual manner. Into this breech B acircular breech-piece, C, is fitted. On the lower end of thisbreeclrpiece a circular collar, m, is made, having recesses or notches1), Fig. III, cut out, for the purpose hereinafter described. Aprojecting arm or handle, D, is likewise fastened to said breechpiece,for the purpose of turning the same. Near the end a spring-bolt, w,situated in the breech B, is made to fit into this handle D, for thepurpose of locking the same, and holding thereby the hole 3 in the upperpart of the breech-piece in a line with the bore of the gunbarrel.

In the upper part of the breech-piece O a hole, 3, is made correspondingwith the bore of the gun-barrel, and on the opposite side of said hole 3a recess, 2, is made in the breechpiece, into which the nipple 4projects, which latter is screwed into the breech-piece, and providedwith a hole passing either through the same or passing on one side ofsaid nipple 4, and communicating with hole 3. On the lower side of thebreech B a projection, 60, is made, acting against the under side ofcollar m of the breech-piece O, for the purpose of holding the same up,and in its place. opposite to the nipple 4, a pin or bolt, It, is fittedthrough the breech B, operated by the hammer H. This bolt h is made tomove easily inward or outward, and is kept in its place by a small pin,0, working in a recess in said bolt h. The action of the hammer Hagainst the bolt h forces the same inward against the percussion-cap onthe nipple 4, igniting or exploding the same,when the gases of theexploded powder pass through the nipple-bore and act upon the shotsituated in the hole 3, propelling the same through the bore of thebarrel.

To charge the gun the breech-piece O is turned one-quarter round, whenone of the recesses 19, made in the collar m, comes over the projection00, and allows the same to pass, when the breech-piece can be pulledout. A shot is then put into the hole 3, and a percussion-cap upon thenipple 4, and the breechpiece put back again in its place and turnedround until the spring-boltw locks the handle D, when the gun is readyto be fired again. Before the breech-piece O is taken out, the hammer Hmust be half-cocked to allow the bolt h to be pulled or pushed outward.to allow the breeclrpiece to be turned around.

I do not claim, generally, a movable breechpiece; but

What I claim as my invention, and desire to secure by Letters Patent, is

The herein-described movable breech-piece, when said breech-piece isheld in its place by a bayonet-j oint, and is removed out of the breechfor the purpose of receiving the charge and the percussioircap aftereach discharge of the gun.

F. DENZLER.
